Orbital ATK, a global leader in aerospace and defense technologies, today announced significant progress on the industry’s first commercial in-space satellite servicing system. The Mission Extension Vehicle-1 (MEV-1) spacecraft successfully completed its critical design review earlier this year and is now in production with about 75% of the platform and payload components already delivered to the company’s Satellite Manufacturing Facility in Virginia. The spacecraft will begin system-level testing in spring 2018 with launch planned late next year. MEV-1 will provide satellite life extension services to its anchor customer, Intelsat S.A., beginning in early 2019.
